Pisces, the last sign of the zodiac and the final water sign, lives between dreams and reality. In ancient times, jovial Jupiter ruled Pisces. With the discovery of Neptune in 1846, astrologers observed that the foggy, hazy, mysterious planet Neptune delineated the Piscean character more fully. Today, astrologers consider both Jupiter and Neptune as co-rulers of Pisces. The influence of Jupiterian good humor helps Pisces when oceans of emotions threaten to drown her. Her great strength and her great challenge are the same: feeling.
